Simplesat has a 0.3-meter optical telescope and a GPS attitude control system. It is intended to test methods for building cheap astronomical satellites and controlling them from a cheap ground station. The 52-kg, 0.48-meter diameter, 0.66-meter high octagonal cylinder Simplesat was developed by NASA-Goddard. Two months after the launch, there has been no contact with the Simplesat astronomy test satellite and it now seems probable that the satellite failed.
